The XCorr exact p-value algorithm has been integrated into the Crux mass spectometry analysis toolkit. Crux toolkit release 2.1, containing the integrated code, is available as precompiled Linux, Macintosh, and Windows binaries, or in source form, all of which may be downloaded here. XCorr exact p-values can be computed using Crux's tide-search command with the --exact-p-value T command line flag.
